Quadropolis: Monument – Charles Bridge is a promotional tile for Quadropolis that can replace one of the monuments in the existing game. Monuments — which are used only in the game's expert mode — are rare buildings that earn you victory points when placed next to parks, shops, or public services in the city that you build, but cost you points when placed next to harbors or factories.
Quadropolis: Monument – Charles Bridge is a promo tile available exclusively for the launch of Quadropolis in the Czech market. To use this tile, replace the monument tile in the base game that bears the same ID number as the promo tile. (Monuments with the same ID number cannot coexist in the game, even if they have different final letters.)
